Cheap HP, full time fan?

[rustedrotors]

Had a thought the other day. IF you can turn the fan on manual, would you have less heat soak issues with the intercooler?

I drive my car in the summer only, so I got some time t play with this idea. Anybody have a wiring schematic for the car?

I would get better cooling on my oldsmobile cutlass by lowering the air dam under the radiator. Wondering if something similar can be done with the ustang too. Force more air to the intercooler rather than under the car.

Washing the radiator with a hose from time to time can be worthwhile too.

You want replace the factory IC not put a fan on it

I've had three of my various turbos with fans mounted for extra cooling, and they are as effective as adding a larger intercooler—if you can! Sometimes there just isn't room to go bigger. In fact, I once replaced an air-to-air with a water-to-air because there was more room for the WTA accessories than a bigger intercooler. WTA can also have an advantage if you plumb it to use the outlet from the air-conditioning evaporator to further cool down the water. Fact is, that is exactly what Chrysler does with the Hellcats.

There are all kinds of cooling upgrades to be performed on an Ecoboost Mustang, and not just the intercooler.

Radiator, oil cooler . . .

I do not know how much the intercooler has changed from the S550, but this guy:

picked up 20 whp on the dyno with just an intercooler upgrade, no tuning.

"Our Mustangs can handle around 7 minutes of hard ciruit racing before the engine begins to suffer from heat soak.​

​

After minute 7, you’re just stuffing hot boost back into the engine."​

Gain 20hp or not lose it on the second and third run?

I saw the video those guys put out trying to compare intercoolers, it was a terrible test

I don't know the answer, robvas. All I have is the linked article.

Just a simple switch. Wanna drive it nutty, flip the switch on. Haven't looking into schematics yet. I can imagine the fan is variable speed, maybe force a 5v isgnal to the fan controller kind of thing.

Im guessing here, but the fan turning on and off is only based on air conditioning and coolant temp, not intercooler outlet temps.

Probably the only mechanical mod I will do is an intercooler upgrade at some point. Maybe an oil cooler. I do have camber plates to put on, but to reduce camber. Seeing what rotating tires each oil change does. Don't mind doing that.

However, my winter car is having a hard to see oil cooler problem. The oil is too cool. I'm getting alot of sludge and foam in the engine. No coolant loss, even slight. I covered up the lower half of the radiator air intake, / grill. seems to go away now. I m thinking the oil cooler bpyass valve is stuck cooling oil 100%. Just as 2014 jetta 2.0 n/a beater. Snowbank surfing the catskills on my way to work.......

With my tunes, I set the grille shutters open 100% all the time and set the fan to come on at 180 and not 212 like stock. It helps a ton. I wouldnt do this on cars that will be driven in winter locations. But in summer in FL, its been great.

Attached are schematics, highlighting fan logic and operation in a 6G.

Before delving into switches for the fan assembly, I'd consider two other factors:

- Airflow across the front of the car, into and out of the engine bay. There are several track cooling threads and sites, all with tips on how to maximize cooling with modest to extensive changes

- Process. The motorsports I follow, drivers will have a warm-up, hot laps and later cool down period. On the street you cannot always choose when or how long you cool down, but you have an out for that: the A/C unit; turning the system on will engage the fans when the car is slow or idling.

As to specifically cooling the intercooler while driving, IDK if the fans being on would be much help. I think maximizing airflow into and out of that area would be more beneficial. [Edit: to include relocating the intercooler or buying a larger one. ] For example, you're already moving forward at a given rate. Having that, then a fan, . How much more air is a fan going to move? But if you've adjusted the area, making it more free-flowing and possibly concentrated, that could have a more positive effect.

YMMV.

Was thinking more of the fans at low vehicle speed or just getting the intercooler cooled down right off the the light.

Got to peek in my car some now. See how the air louvers effect things on here. Im not afraid to remove a few louvers or all. I live in NY, but only drive april to november, and often just on nice days too. Still got to keep the winter car's brakes clean once twice a week.

Do you know if changing fan operations can be altered via forscan…

tks

I'd like to think so. In post #10 above, that graphic of the temps and fan load, that's a capture of someone's tuning software. But also in post 10, I wonder how effective a fan would be, at speed. If I'm already jammin' around the track, the fan spinning might not help all that much. Fans at 100% during cooldown laps and before or when returning to pits, that could be useful.

While the fan is one bit, I'd also study the cooling of everything. Enclosed is a link to one track-related thread at 6G. If it involves the track and cooling, there's probably something about it there. Could give anyone a lot of ideas and things to consider.

… yes that’s why I asked lol

I’ve done a number of engines, just new to the 2.3l MPC 2024-26
Used water wetter for years, got a 5.0 thermostat 180*, oil filter cooler fitting still sizing cooler, etc.

Anyone know of similar thread but for the MPC? Or someone that built a complete engine using the EcoBeast block.

All of this really relies on what you plan on (or are) doing with the car. A soccer mom doesn't need extra oil cooling or a larger radiator/intercooler. Now if we're talking boy racer, all the goodies might give you an edge, but sooner or later John Law and/or an unintended drift is going to cost you big time. My Eco-Boost is a city car, and gets driven a bit less than my '19 Ranger. They both have Ford Performance Tunes, which makes them more responsive, with the extra performance an added bonus. Or should I say boost?
